illustrated by the patent to J Aitchison, No.

510,149, patented December 5, 1893, and is an improvement in the details of a construction for which I have already applied [or Letters Patent.

The object of the invention is to better protect the primary llame ol' the wick from undesirable air-currents and prevent all pos sibility of vapor (minimisation onthe inside surfaces of the inner wick-tube.

Referring to the drawings, Figure 1 represents a vertical section taken through a burner with the lower portion of the wicktubes and the upper part oi the con'1bustio'1-i chamber broken away, the details of the features thus omitted being well known in the art. Fig. 2 represents a plan view of the wick-tubes and air-guard shown in Fig. 1. Fig. 3 represents a vertical section showing a modification of the air-guard illustrated in the preceding views. Fig. 4 is a plan view of r the wick-tubes and air-guard shown in Fig. 3.

in the drawings, is the inner wick-tube, and 2 is the outer wick-4 tubes Between these tubes is a wick 3, which is raised or lowwick-tube, being of a slightly larger. diameter than thesaid wick-tube to leave a narrow air.- assage 5 between its upper end and the wie -tube. The top of this'collar is in a i plane slightly above the wick-tube, as shown,

and the air-passage 5 mentioned is considerabl narrower than the air-passage provided in amp devices vrhichburn with a yellow .top. edge of thehollar 4. "At t flame. v

6 is a chimney the bottom of which rests on the collar andgextends up to a suitable height. 'f

7 is-an air-deflecting plate or-spreaderapproximately the diameter of the wick and sup orted in a position slightly above the wic as shown, and a little'higher than the e top of the inwardly and the inner edge 9 of which extends upwardly to a plane slightly above the top edge of the wick-tubes and forms a bar- 'I rier toprevent the swiftly-moving air-current which flows through the interior of the burner from impinging on the base of the wick This member 8 is shown as a flange joined firmly to the inner wicletube, as shown in Figs. 3 and 4, or may be made integral therewith, as shown in Figs. 1 and 2.

I in this class of burners if the: base of the wick is not protected from the swiftly-movmg air-currentthe efiect will be that no combustion can occur at the base'of the wick where it emerges from thewick-t be and the burner will not give a proper flame. In the operation oi this device there is a drift of vapor inwardly over the projecting member or flange 8, and by making this member or flange integral or firmly fixed to thetop of the inner wick-tube there is no such vapor drifting downward y and con- (lensing on the inside ofthe wick-tube. In the first lighting of the-wick in these devices it is desirable that a small measure of air gain access to the inner base of the wick, so that the initiatflame at this point will be started inner wick-tube is a member 8, which extends possibility of readily, and for this purpose I provide a number 'of small air-openin s- 10 through the member 8, as shown in *igs. 1 and 2, as by this means the, wick can be initially lighted -1nore satisfactorily and with the top of the wick below the plane of the air-barrier; The spreader 7 is supported a little distanceabove the wick in any suitable manner and leaves a lateral air p'assage between itselfand the flange 8. The air passing'swiftly through this passage outwardly carries the partiallyeonsuined vapors from the wick outwardlythrough the opening formed by the edge of .saidspreaderand the top edge of the collar {1,

producing a blue flame, the barrier 9 prevent-" ing such current l'romstriking the lower part of the exposed portion of the Wick, and thus 1 0O protecting it so that a small primary flame is I, tube, and a spreader extending across the tops of said tubes and forming an airway.

therewith, said inner tube being provided with aflangeiextending inwardly from the upper end and having a portion toward. the mterior of the burner on a higher plane than the portion adjacent to the inner wick-tube to form an airbarrier,- substantially as specified. l

2 In a burner'of the class described, the combination of an inner and an outer wickt ube, a spreader extending across the tops of said tubes and forming an airway therewith, and a flange projecting inwardly directly from the top of the inner wick-tube and hav- 'ing a portion toward the interior of the burner on a higher plane than the top of the inner wielK-tube,substantially as specified.

3. In a burner of the class described, the

, combination of an inner and an outer wit-lo tube, a collar surrounding said tubes with its top edge. above the plane of the same, a spreader extending across the tops of said tubes and having its outer edge on a plane above the top edge of the collar, and a flange extending inwardly directly from the upper end of the inner wicletube and having a portion in a higher plane than the top of the said wicktube to form an air-barrier, substantially as specified. p 47 In a burner of the class described, the combination of an inner and an outer wicktube, a collar surrounding and spaced from the outer wick-tube with its upper edge in a higher plane than thetop of said wick-tube, a spreader extending across the tops of said wick-tubes with its outer edge in a plane above the top edge of the collar, and a flange extending inwardly directly from the upper end of the inner wick-tube and having a portion above the plane of the top of said tube to form an airbarrier, substantially as specified.

5. In a burner of the class described, the combination of an inner and an outer wicktube,-a spreader extending across the tops of eeaeae to form an air-barrier for protecting the base tube, a spreader extending across the tops of said tubes and spaced therefrom to form an airway therewith, and a flange projecting inwardly from the upper portion of the inner wick-tube and having a portion thereof in a higher plane than the top of said tube to form an air-barrier, said flange being provided with perforations for admitting air in limited volume therethrough.

7. In a burner of the class described, the combination of an inner and an outer wicktube, a spreader extending across the tops of said tubes and forming an airway therewith, and a flange projecting inwardly from the upper end of said wick-tube and having a portion toward the interior of the burner on a hi her lane than the to of said wick-tube n 1 said flange being provided with perforations below the said portion for admitting air in r limited volume thercthrough.

8. In a burner of the class described, the combination of an inner and an outer wicktube, a collar surrounding the outer wicl tube and spaced therefrom and having its upper edge above the upper edge of said wick-tube, a spreader extending across the tops of said tubes with its outer edge above the plane of the upper edge of the collar, and a flange extending inwardly from the upper portion of the inner wick-tube and having a portion on a higher plane than the top of said tube for the purpose of forming an air-barrier, therc'being perforations in said flange to permit the passage of a limited volume of air therethrough.

9. In a burner of the class described, the combination of an inner and an outer' wield tube, a collar surrounding the outer wicktube and spaced therefrom, and having its upper edge above the upper edge otsaid wick-tube, a spreader of less diameter than the said collar and extending across the tops of the wick-tubes and forming an airway therewith, said spreader having its outer edge above the planeof the upper edge of the collar, and a flange extending inwardly from the top of the inner wick-tube and having a' portion toward the interior of the inner tube on a'higher plane than the-portion adjacent to said tube for forming an air-barrier, said flange being provided with perforations be low the highest portion or barrier thereof for admitting air in limited volume therethrough, substantially as specified,

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
